We're hiring a Data Engineer (5+ years) to independently design, deploy, and operate production-scale data platforms in fully air-gapped, secure customer environments — no cloud dependency, with manual deployment and troubleshooting expected. The ideal candidate has hands-on experience with Apache Airflow, Spark, PostgreSQL, Docker, Python, SQL, and S3-compatible storage (MinIO), along with strong knowledge of geospatial and time-series data, and is comfortable owning infrastructure end-to-end without managed cloud services — from data pipelines to deployment to troubleshooting in fully isolated environments.

Proven experience deploying via Docker/Docker Compose in air-gapped or restricted-network environments
Comfortable working in Ubuntu-based environments with manual/local infrastructure management
Strong proficiency in Python, SQL, Airflow, Spark, and PostgreSQL
Experience with geospatial and time-series data
